A one-ton sample of quartzite was shipped to an independent lab Dorfner Anzaplan, in Germany, for mineralogical analyses through X-ray diffraction analysis, chemical analyses through X-ray fluorescence spectroscopy, grain size distribution, mineral processing analysis, automated optical sorting, and thermal stability testing. The sample was crushed and screened into fractions between 20 - 120 mm for evaluation of applicability of these fractions as feedstock for metallurgical-grade silicon production.

Results indicate that the material, after comminution and classification fraction, is of high initial purity (99.5 wt.-%), making the fraction chemically suitable as medium quality feedstock material for metallurgical-grade silicon production.

MGX operates three silicon projects in southeastern British Columbia- Koot, Wonah, and Gibraltar.

About Gibraltar Silica Property

Gibraltar is located approximately 95 kilometers northeast of Cranbrook, BC (B.C. MINFILE 082JSW001). The Property features high purity quartzite that has potential for technological applications, consisting of snow white coloured, high purity silica that contains >98.8% SiO2 and < 1.2% impurities such as Al2O3, Fe2O3, CaO, MgO, Na2O, K2O. The Gibraltar quartzite unit is located in the foreland thrust zone of the Hughes Range of the Rocky Mountains. It covers a sedimentary clastic-carbonate rock package located near the confluence of Kootenay and White River. Sedimentary rocks generally have a north-northwest strike, but locally a north-northeast strike is prominent. Minor folding was noted in the carbonate sequence immediately adjacent to quartzite unit. Two westerly dipping thrust faults (Hay, Carter, 1988) are believed to run north-south close to the eastern edge of the Gibraltar property.

Energy Applications

To further the Company's expansion into low cost energy mass storage systems, following the acquisition of ZincNyx Energy Solutions (see press release December. 13, 2017), MGX has prioritized evaluation and development of its silicon projects for silicon metal potential. One of the primary uses of silicon metal is in solar panels. Solar panels are a cornerstone to remote and distributed energy solutions. Solar, combined with a mass storage system such as that currently under development by ZincNyx, serves to replace or augment diesel generators, as well as having broad applications in energy storage for residential and commercial grid load balancing and backup, and in providing primary and backup power for industrial sites, telecommunications, large scale computer server arrays and military bases. Additional information on the integration of solar with ZincNyx energy storage systems is available at www.zincnyx.com.
